I have never succeded in using any other cd than 2006.0 on an USB stick. Try that one and see if it works better or not.

If you dont want to try the older minimal cd on the USB stick you have to do some major changes on the setup as it doesnt seem to find the USB for some reason at that point. Maybe some extra delay or something would do it._________________HP NC 4010, Pentium-M 725 1.6GHz w/ 1Gb RAM, 60Gb Hitachi Travelstar.
Running Gentoo-2.6.21-r4 (again as 2.6.22 kernels hogs CPU), all but SD reader works fine.

It's a typo. I wanted to ask what filesystem is on sdb1... it probably doesn't matter anyway.
I only asked because there were some problems mounting fat32 with the 2006 livecd, but I don't think that is the case with 2007.0.

OK, I put 2007.0-r1 again on my flash drive. Same error, I typed shell then and had to 'mkdir -p /mnt/cdrom'. But I could't mount it by typing 'mount /dev/sdb1 /mnt/cdrom'. Sdb1 was listed in /dev. Weird

I got the same problem. I know that the HOWTO required 1GB drive and the LiveCD image, but I only have 512MB drive, so I copied the MinimalCD image on it. I suppose that the problem is that the kernel in the minimal version does not support codepage 437.

Sooo...

Is there any easy fix to that? I know that I could just use 1GB stick, but I don't have one... So maybe copy kernel from the LiveCD into MinimalCD? Or Copy the big LiveCD image to the stick and truncate the last 200 megs and pray for it to work?

How come? When I do all the steps described in the HOWTO and then run syslinux, it complains that it couldn't find a valid FAT filesystem...

Anyway, I tried to do the following: I mounted the LiveCD image (where the kernel is good) and replaced the image.squashfs file with the one coming from the MinimalCD (because its small). Then I copied everything into USB stick, ran syslinux etc. So basically I created a hybrid . And it almost works... The kernel still can't mount the /newroot, but when I enter shell, I can mount my stick and the squashfs on it. However, I can't make the boot process resume. Any ideas?

Ok so I used ext2 and instead of syslinux I run extlinux on mounted usb's file system (as it wished):

Code:

extlinux -i /dev/sdb1

This time, first of all I have to write 'gentoo' at prompt, then after drives detection kernel panic occurs. Is says it couldn't find root and ask for 'root=' append. I run then with 'root=/dev/sdb1' append but it still halts. Damn it..

Hey, can you tell exactly how did you prepare the USB stick? I still can't make it work :/.

Also, I tried to install GRUB on the stick, but still no success. Anybody knows what does it mean when GRUB only displays "GRUB ", nothing else and then hangs?

I've been having the same problems as described. My solution was to use ext2 on the usb flash drive. A couple of gotchas though. Make sure your usb drive is mounted before you issue the "extlinux -i /dev/sda1" command (be sure to substitute sda1 with the correct device for your usb drive). And then you have to mv, ln or cp your syslinux.cfg file to extlinux.conf. (eg. cp /mnt/usb/syslinux.cfg /mnt/usb/extlinux.conf). Once I did those 2 things I was able to boot the 2007.0 minimal CD from my usb flash drive.

Yea, like a week ago I did something like this with ext3 but didn't work.. but I'll try with ext2 as soon as possible

For the record, I was following http://www.gentoo.org/doc/en/liveusb.xml. I basically followed that step by step, except I used the 2007.0 minimal boot cd and of course, I substituted creating a fat16 partition for ext2 and used extlinux instead of syslinux. Here is a condensed step-by-step (using /dev/sda as our usb drive):

Lol I unconsciously did the same thing as in quoted text, and it still doesn't work, kernel panics!
Can you help me how to figure out correct root for me?
